Pricing & cost

Pricing ModelHybrid pricing model: Merge.dev offers a self-serve tier ('Launch') with published per-linked-account rates, alongside custom quote-based annual contracts for higher tiers ('Professional' and 'Enterprise'). Pricing is primarily determined by the number of active 'Linked Accounts' (individual end-user connections to integrations), platform tiers, and enabled API categories. ↗

Typical CostThe self-serve Launch plan provides the first 3 production Linked Accounts free, costs $650/month for up to 10 Linked Accounts, and charges $65/month per additional Linked Account. Higher-tier custom annual contracts range from $15,000–$30,000/year for Starter deployments to $120,000–$250,000+/year for Enterprise deployments, with a median annual contract value of $88,603/year according to Vendr transaction data. ↗

Api Or Integration FeesEach end-customer integration connection is charged as a separate Linked Account ($65/month per extra account on Launch). Custom integration development and non-standard integrations are billed separately at $10,000–$50,000+ per custom integration. Additional costs may apply for enabling extra API categories, higher data sync frequencies, passthrough requests, or overages. ↗

Implementation CostBasic go-live support and onboarding are included in custom Professional and Enterprise plans (with white-glove onboarding for Enterprise). Separate professional services and custom integration development fees range from $10,000 to $50,000+. ↗

API & data access

Has ApiYes ↗

Api TypeREST API ↗

Api Access GatingAPI access requires authentication via Bearer API keys and account tokens. Merge offers a freemium Launch tier where the first 3 production linked accounts are free ($650/month base up to 10 accounts, plus $65/month per additional account). Advanced features including custom field mapping, field-level scopes, and custom sync frequencies are gated behind paid Professional and Enterprise custom contracts. ↗

Api LimitationsRate limits are enforced per Linked Account based on tier: Launch (100 requests/min), Professional (400 requests/min), and Enterprise (600 requests/min). Write operations have narrower coverage than reads across integrations. Access to custom fields and configurable sync schedules requires Professional or Enterprise plans, and sync resyncs are limited by allocated sync credits. ↗

Data Export OptionsMerge provides scheduled automated data exports via Merge SFTP (normalizing recurring report outputs into Common Models) as well as manual CSV file uploads and dashboard CSV export capabilities via Merge Link. ↗

Native AI features

Ai Features SummaryMerge.dev (Merge Unified API) is a developer integration platform for B2B SaaS rather than trade/construction field management software. Its native AI capabilities center on AI agent infrastructure, specifically Merge Agent Handler (launched GA October 2, 2025) and the Merge MCP Server (GA released April 2025), which allow third-party AI agents and LLMs to authenticate, query, and execute actions across 220+ SaaS integrations via the Model Context Protocol (MCP). It does not contain native field service automation tools such as estimating or CSR. ↗

Ai DispatchNone. Merge.dev does not offer native AI-powered dispatching or scheduling software for field operations. In Merge's technical documentation, 'dispatch' refers strictly to API request routing within its Agent Handler gateway. ↗

Ai FinanceNone. Merge.dev does not provide native AI invoicing or AP/AR automation tools. It offers an Accounting Unified API and corresponding MCP tool endpoints, which allow external AI agents to read/write data in third-party accounting platforms (e.g., QuickBooks, NetSuite), but it does not ship built-in financial AI features. ↗

Ai Assistant Or McpYes (Shipped/GA). Merge.dev offers the Merge MCP Server (released April 2025) and Merge Agent Handler (launched October 2, 2025). This infrastructure exposes Merge's unified API connectors as Model Context Protocol (MCP) tools for LLMs (such as Claude Desktop, Cursor, and custom AI agents), enabling natural language queries, entity creation, and updates across connected SaaS systems, enforced by enterprise security rules, DLP, and logging. ↗

Integrations & ecosystem

Accounting IntegrationsMerge.dev connects to general cloud and enterprise accounting systems including QuickBooks Online, Sage Intacct, Sage Business Cloud, NetSuite, Xero, FreshBooks, Zoho Books, Wave Financial, Clear Books, FreeAgent, Microsoft Dynamics 365 Business Central, Moneybird, Oracle Fusion Cloud ERP, and Workday. It does not natively support specialized construction accounting systems such as Foundation Software. For general project and workflow management, Merge connects to tools under its Ticketing Unified API (e.g., Asana, ClickUp, Jira, Basecamp, Azure DevOps), but does not maintain native connectors for trade/construction-specific field platforms like Procore or ServiceTitan. ↗

MarketplaceMerge.dev features a public Integrations Directory listing over 240 supported applications across categories such as Accounting, HRIS, ATS, CRM, Ticketing, File Storage, Chat, and Knowledge Base. It also maintains a dedicated Partner Network directory and provides an Integration Metadata API (`/api/integrations`) allowing B2B software vendors to programmatically power in-app integration marketplaces. ↗

Unified Api SupportMerge.dev is itself a Unified API provider, offering unified data models (Common Models) that act as a third-party middleware abstraction layer rather than direct, native point-to-point integrations. For trade and construction contractors requiring deep connections between specialized field management tools (e.g., Procore, ServiceTitan) and trade ERP/accounting platforms (e.g., Foundation, Sage 100 Contractor, Sage 300 CRE), vertical-specific unified API connectors such as Agave API are used. ↗

Accounting fit & implementation

Certified PayrollNot supported natively or via add-on; Merge.dev standardizes standard payroll and HRIS data models (e.g., Employee Payroll Runs) but does not provide Davis-Bacon certified payroll reporting (Form WH-347) or prevailing wage compliance features. ↗

Accounting MethodSupports both accrual and cash-based accounting data fetched from underlying accounting and ERP systems, providing access to invoices, journal entries, accounts, balance sheets, and cash flow statements. ↗

Wip Poc SupportNot supported natively; while Merge provides generic accounting models such as Projects, Invoices, and Journal Entries, it does not natively calculate or generate construction-specific WIP (Work in Progress) or percentage-of-completion schedules. ↗

Implementation TimeTypically days to a few weeks for software developers to build integrations, with end-user account linking taking minutes via Merge Link. ↗

Requires ImplementerNo paid implementer or VAR required; Merge.dev is a developer-first API middleware platform designed for direct integration by software engineering teams. ↗

Adoption & market position

Market PositionMerge.dev is a modern B2B integration infrastructure platform that provides unified APIs across HRIS, ATS, payroll, CRM, accounting, ticketing, and file storage categories, as well as AI agent governance tools (Merge Agent Handler). Contrary to the premise, it is not a field-level software product built directly for U.S. trade or construction contractors; rather, it is a developer platform used by software vendors (including construction-tech SaaS providers) and enterprise IT teams to build and maintain third-party software integrations. — Forbes (https://www.forbes.com/profile/merge/)

Customer ScaleMerge serves approximately 1,700 business customers as of early 2026 (including software and enterprise clients like OpenAI, Mistral AI, Ramp, and Calendly), up from 2,500+ integration implementations tracked in prior industry reports. Because Merge functions as backend developer infrastructure rather than a contractor-facing app, specific numbers of end-user trade contractors using products integrated via Merge are not publicly segmented. — Forbes (https://www.forbes.com/profile/merge/)

MomentumMerge demonstrates strong growth momentum as a modern, category-leading platform. Named a sole Category Leader by G2 and included on the Forbes Fintech 50 and Forbes Next Billion-Dollar Startups lists, Merge has raised $75 million in total capital—most recently a $55 million Series B led by Accel in October 2022 at a $325 million valuation. Company financials reflect revenue expansion from $8 million in 2022 to $14 million in 2023 and an estimated $20.8 million in 2024. — Business Wire (https://www.businesswire.com/news/home/20240214309322/en/Merge-Reports-Record-Customer-Growth-in-2023-with-60-Increase-in-New-Customer-Logos)
